Lots of money for a parcel (6)
I believe the answer is:
packet
I believe this is a double definition.
'lots of money' is the first definition.
'a parcel' is the second definition.
(packet is a kind of parcel)
'for' is the link.
(Other definitions for packet that I've seen before include "Parcel - mail boat" , "An awful lot of money" , "Boat; paper container" , "Large amount of money" , "Sachet" .)
